FEEDING ATTACHMENT FOR CYLINDE-R PRINTING-PRESSES.

SPECIFICATION forminglpart of Letters Patent No, 317,929, dated May, 12, .1885. Applicationhled July 25, 1884.' (No model.)

To all whom, t may concern:

Be it known that I, SANFORD C. Cox, of Lafayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Feeding Attachments for- Gylinder Printing-Presses; and I do hereby declare that the following is a full, clear, and exact description t-hereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to feeding attachments for cylinder printing-presses; and ithas for its object to provide a device which shall be simple, inexpensive, entirely automatic in its operation, and which may be easily attached to any cylinder-press of ordinary construction.

The invention consists in the construction and combination of parts, hereinafter described, and pointed out in the appended claims.

In the drawings, Figure 1 is a side view of a machine embodied in my invention. Fig. 2 is a front part-sectional view of the machine, and Fig. 3 is a sectional view of the carryingcylinder.

The same letters refer tothe same part in all the figures.

A designates the frame of the machine,4of suitable construction; B, the platform or bed for the imprinted paper, and() the transverse gage-board against which the edges -of the sheets rest before being delivered to the press by the suction cups, hereinafter described. The frame is provided to each side with par' allel segmental-shaped tracks D, provided with upwardly-beveled edges7 V-shaped in transverse section, as shown in Fig. 2, and having for their centers a pair of studs, E, secured in the sides of the frame and carrying levers F and F2, the former of which is provided with a downward-extending arm, G, having a slot, II, in which works a crank-pin, I, secured to awheel or disk, J, mounted upon one end ofthe operating-shaft K. The levers F and F2 are provided near their upper ends with slots L, receiving pins M at the ends of a double crank shaft, N, which is mounted transversely in the frame, and which serves to convey the oscillating motion imparted to lever F by the operating-shaft to the lever F2. The upper ends ofthe levers F and F2 are provided with triangular slots O, into which pass the ends of the rollers P, journaled on the ends k of the tubular carrier Q, and carrying the roller-wheels It. rlhe said roller-wheels are provided with circumferential grooves V- shaped in section, and are thereby adapted to travel over the V-shaped edges of the ways D. The underside of the carrier Q is provided with the suction-cups S, which communicate with its hollow interior, and havegsecured around their edges the rubber rings s, to cause them to adhere to the paper when the air is exhausted from the carrier and cups. One end of the tubular carrier is closed, and the other end is connected by a flexible tube, T, with an air-pump, which is not shown in the drawings, but which is operated from the cylinder or operating-shaft of the press, and which is so constructed and arranged that it shall exhaust the air from the carrier when the latter reaches the paper-table, and cease operation and permit air to enter the carrier 7' when the latter reaches the end of its stroke. The ends of the segmental tracks D are vertical or abrupt, and the triangular slots O in the carrying-levers will permit the carrier to descend the required distance at either end and will again raise or lift it at the beginning of the movement in the opposite direction. By this construction the suction-cups will always descend squarely upon the paper, and

will never fail to deliver it evenly and smoothly.

From the foregoing description., taken in connection with the drawings hereto annexed, the operation of my invention will be easily understood by those skilled in the art to which it appertains.

I will state that when desired and when rendered possible by the construction of the frame thelevers F and Fl may be mounted upon a transverse shaft U, as shown in dotted lines in Fig. 2, said shaft taking the place of the studs-E.

I claim and desire to secureby Letters Patent of the United States-- 1. In a feeding attachment for printingi presses, the combination of a frame having IOO segmental tracks, a tubular carrier traveling upon the said tracks and provided with suotion-eups, as set forth, a pair of levers provided with triangular slots at their upper ends, through which extend boxes journaled upon the ends of the carrier, and operating mechanism, substantially as set forth.

2. The combination ot' the frame A, ways D D, carrier Q, rollers P, and roller-Wheels R with the vibrating levers F F2, pivoted on the bosses E and provided with the slotsL and O, substantially as specified.

3. The combination of the frame A, levers F F2, having the slots H, L, and O, double crank-shaft N, rotating disk .T, having the wrist-pin I, and tracks D D with the Carrier Q, provided with the suction-cups S and moved back and forth over the Ways D D by means of the engagement of the levers F F2 With the rollers P, journaled on the ends of the oarrier, and the roller-Wheels R,seoured to said rollers, substantially as set forth.

In testimony that I claim the foregoing as my own laffix my signature in presence of two witnesses.

SANFORD C. COX.
